== Faults and maintenance ==

* The disc unit supply's RIFA X2 capacitor and start-up electrolytic fail as in other Acorn supplies; a weak start-up capacitor makes the supply slow to start. See [[BBC Master Compact Capacitor Guide]].
* A continuous tone with a blank screen has been traced to failed DRAMs on several Compacts. See [[BBC Master Compact Troubleshooting]].
* The membrane keyboard cannot be repaired key by key; Acorn's manual says to replace the whole keyboard if no track fault can be found.<ref name="smcff">Acorn Computers, ''[[BBC Master Compact Service Manual|Master Series Compact Microcomputer Service Manual]]'', 0458,002, 6 "Fault finding", printed pp. 26–38 (6.1.8: individual keys cannot be replaced on this keyboard).</ref>
* Routine care is in [[BBC Master Compact Maintenance]].
